Method and apparatus for reducing the thickness of a sensor stack in a current-perpendicular-to-plane GMR/tunnel valve sensor |
| 摘要 |
A method and apparatus for reducing the thickness of a sensor stack in a current-perpendicular-to-plane (CPP) GMR/tunnel valve (TV) sensor is disclosed. A layer of alpha-Fe<SUB>2</SUB>O<SUB>3 </SUB>having a high coercivity is formed adjacent the active areas for pinning the bias layer.
